ASTM E2625 - Standard Practice for Controlling Occupational Exposure to Respirable Crystalline Silica for Construction and Demolition Activities
These practices and criteria were developed for occupational exposures during construction and demolition activities. They are intended to (1) protect against clinically significant disease from exposure to respirable crystalline silica, (2) be measurable by techniques that are valid, reproducible, and readily available, and (3) be attainable with existing technology and protective practices.

Effects of occupational exposure to respirable quartz dust on acute myocardial infarction
Objectives: The aim of this study is to investigate the effects of occupational exposure to respirable quartz (RQ) on first acute myocardial infarction (AMI). RQ causes pulmonary diseases like silicosis and has also been linked to cardiovascular diseases. Inflammation is hypothesised as the underlying pathway. Methods: We performed a 1:3 matched case–control study nested in a cohort of male uranium miners. We included cases (identified from hospital records and validated according to WHO criteria) who had suffered their first AMI while still employed and <65 years of age. Controls were...
Exposure-response relationships for silicosis and its progression in industrial sand workers
Objectives: This study aimed to characterize the relationship between radiographic silicosis and exposure to respirable quartz and determine how exposure affects disease progression. Methods: Surveillance chest radiographs from a cohort of 1902 workers were examined to identify 67 cases of radiographic silicosis and 167 matched controls. Exposures were estimated by linking work histories to a job exposure matrix (JEM) based on samples collected by the participating companies and historical estimates. Conditional logistic regression was used to examine exposure-response relationships. Sequential...
Outbreak of silicosis in Spanish quartz conglomerate workers
Objectives: To describe the epidemiological and clinical characteristics of an outbreak of occupational silicosis and the associated working conditions. Methods: Cases were defined as men working in the stone cutting, shaping, and finishing industry in the province of Cádiz, diagnosed with silicosis between July 2009 and May 2012, and were identified and diagnosed by the department of pulmonology of the University Hospital of Puerto Real (Cádiz). A census of workplaces using quartz conglomerates was carried out to determine total numbers of potentially exposed workers. A patient telephone...
